DOOR.

To all 'whom it may concern:

Be it known that I, DANIEL W. MILLsArs, a citizen of the United States, residing at Viashington, in the District of Columbia, have invented new and useful Improvements in Doors, of which the following is a speciication.

This invention relates to a door of the type wherein provision is made for ventilating the room or the like, in the entrance to which the dooi is mounted.

The primary object of the invention is to provide a door of this character wherein the top and bottom rails of the door are spaced from the ends of the stiles to pro- `Vide the door wth Ventilating openings which are normally closed by panels hingedly connectedl with the above-mentioned 4rails to permit the panels to be moved to a position wherein the Ventilating openings will be unobstructed thereby.

Another' obj ect of the invention is to provide a door wherein the panels may be yieldably, yet lirmly held in position to obstruct the Ventilating openings by springs, the connection of which with the door and the panels is such, that when the panels have been moved to a position wherein the Ventilating openings are unobstructed thereby, the spring will not exert an influence"y upon the panels tending to restore the panels to their normal position.

A further object of the invention is to so recess the rails and panels which serve Vas closure members for the Ventilating openings that the door has formed therein pockets for the reception of the springs which firmly yet yieldably maintain the panels in position to obstruct the Ventilating openings in the door.

Vith these and other objects in View, the invention resides in the novel combination and arrangement of parts, which will be hereinafter described and particularly pointed out in the claim.

The preferred embodiment of the invention has been illustrated in the accompanying drawings, although no restriction is necessarily made to the precise details of con- Istruction therein shown, as changes, alterations, and modiiications within the scope of the claim may be resorted to when desired.

.ln the drawings Figure 1 is a View in front elevation of a door constructed in accordance with the invention.

Specification of Letters Patent.

Patented July 23, 1918.

.1 Application filed November 7, 1917. Serial No. 200,835.

Fig. l is a detail sectional View through the top rail and panel associated therewith and showing the panel firmly yet yieldably held in position to close the Ventilating openings adjacent the top of the door.

Fig. 5 is a View similar to Fig. l wherein the panel which acts as a closure member for the Ventilating openings adjacent the top of the dooi` is shown in lowered position.

Like characters of reference denote corresponding parts throughout the several Views in the drawings.

Referring now to the drawings in detail the letter A designates a door constructed in accordance with the invention and which in this instance has been shown of the panel type although I desire it to be understood that other types of doors may be constructed in accordance with the invention if desired.

The door A as constructed in accordance with the invention has the top rail 5 and the bottom rail 6 spaced from the ends of the stiles 7 to provide the door with Ventilating openings 8 adjacent the top and bottom thereof. The rails 5 and 6 and stiles 7 are rabbeted, as at 9 to permit screens 10 to be arranged within the opening A and secured to the stiles to prevent insects from entering a room in the entrance to which the door A is mounted.

The Ventilating openings 8 are adapted to be closed by panels l1 each of which is hingedly connected with one of the rails of the door A and has formed in one end thereof a pair of recesses 12 which open out at one end through the said end of the panel and one side thereof.

When the panels 1l are in position to obstruct the Ventilating openings S the recesses 1Q in each panel register with the recesses 13 in the rail to which the panel is attached, the recesses 13 in the panels correspond in shape to the recesses 12 so that each recess 13 opens out at one end through an end of the rail and one side thereof. The recesses 19. and 13 form within the door A pockets in each of which is arranged under tension a coiled contractile spring 14 and these springs are terminally connected with securing elements 15. The elements l5 are passed through the recesses in the-railsf'and panels and'ra'lso through eyes :fat theterminals of the spring.

Connected with each of the panels 1l -is anoperating rod 16 by means of which the panels may; be' -sw-ungtofa positi-oir uporny the door wherein the panels will not obstruct the openings 8 and to insurethe'panelwhich is connected with therail 6 vremaining in structV the Ventilatingl opening :adj acent the bottom of' the/door -A the operatingirodl Y lthereonmay be held in an out ofthe way position byv engaging :the hook on the rod such position, the montant of f the 'door A has mounted thereon avkeeper 17 -withwhieh maybe engagedfa'hook 18 at one end of the rod 16onfthejpanelwhich is connected with the *raill 6.

`5Through the above described manner of .arranging and connecting the springs 14 Awith'theV rails v'an'dgpanelsll on the dooi1 it will be seen with references to Fig. l inthe drawing that whenthe p anels are in position'toob'struct the openingsfSf-the springs are under tension and'firmly yet yyieldably hold theI panels inA the above mentioned Iposition.

)When thepanels have been moved to open position as shown in`Fig. 5 inthe drawing it will be observed with reference to this figure that by soarrangingfthefvrecesses 12 and 13 that they open out through one side of the railsV and panels the springs are caused to assume a shape corresponding to that of v anrifn'verted U, so that the springsfflieto one side of the hinge connection of the panels with'the railsand Vwith the tension of the springs relaxed, thus, insuring the .panels remaining in openl position.

From'th kforegoing description taken in connect-ion with? the accompanying 'drawings vide openings atthe to'p jandibott'om ofthe door, said rails having recesses1v therein opening out through one side edge ofthe rails,
